Electronics engineers, IoT developers, and embedded systems professionals use this module extensively for building wireless control systems, remote monitoring applications, and mobile-connected embedded projects. It solves the critical challenge of adding wireless connectivity to Arduino, PIC, and ARM-based microcontroller projects without requiring complex RF circuit design or expensive communication protocols.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe HC-06 Wireless Bluetooth Module operates on the Bluetooth 2.0 standard with a Class II transceiver, enabling reliable wireless communication within a 10-20 meter range depending on environmental conditions and antenna orientation. The module communicates via a standard UART serial interface operating at 9600 baud rate by default, making it directly compatible with microcontroller UART pins without requiring level shifters for 5V logic. The baseplate-free design provides a compact form factor ideal for space-constrained embedded applications, while the module maintains full compatibility with standard Bluetooth host devices including Android smartphones, iOS devices, and Windows computers with Bluetooth adapters.\u003c\/p\u003e\n\n\u003cp\u003eThis particular variant without baseplate is engineered for direct integration into custom PCB designs or breadboard prototyping environments, eliminating unnecessary bulk and reducing overall system cost. The module features an onboard antenna for improved RF performance and integrates a complete Bluetooth stack, handling all protocol complexities internally. Power consumption remains minimal at approximately 80mA during active transmission and 8mA in idle mode, making it suitable for battery-powered applications. The slave-only configuration means the module waits for incoming Bluetooth connections from master devices, simplifying the pairing process and reducing firmware complexity for most hobbyist and professional applications.\u003c\/p\u003e\n\n\u003ch2\u003eKey

power supply (depending on your module variant), GND to ground reference, TX pin to your microcontroller's RX pin, and RX pin to your microcontroller's TX pin through a voltage divider if using 5V logic. The STATE pin indicates connection status (high when connected, low when disconnected) and can be monitored by your firmware to trigger specific actions. Program your microcontroller to communicate via UART at 9600 baud rate, sending and receiving serial data that the HC-06 automatically transmits and receives over the Bluetooth wireless link. On the mobile device side, download a Bluetooth terminal application, pair with the HC-06 module using the default PIN (typically 1234 or 0000), and establish a serial connection to send commands and receive data from your embedded system.\u003c\/p\u003e\n\n\u003cp\u003eFor advanced customization, you can send AT commands to the module by connecting it in AT command mode (pull EN pin high during power-up). Common AT commands include AT+NAME to change the module name visible during Bluetooth discovery, AT+PSWD to set a custom pairing PIN, and AT+BAUD to modify the serial communication speed. Always ensure proper power supply voltage and current capacity, as inadequate power can cause intermittent connection drops or module malfunction. Test your connections using a serial monitor before deploying in production, and implement error handling in your firmware to gracefully manage Bluetooth disconnections and reconnections.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between HC-05 and HC-06 modules?\u003c\/summary\u003e\n\u003cp\u003eThe HC-05 module operates in both master and slave modes, allowing it to initiate Bluetooth connections to other devices, while the HC-06 functions exclusively in slave mode and can only accept incoming connections. The HC-06 is simpler to implement, consumes less power, and is ideal for most IoT and embedded projects where the mobile device or computer initiates the connection. Choose HC-05 only if your project requires the microcontroller to actively discover and connect to other Bluetooth devices.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use HC-06 with 5V Arduino boards directly?\u003c\/summary\u003e\n\u003cp\u003eThe HC-06 RX pin is 3.3V logic level, so connecting a 5V Arduino TX pin directly can damage the module over time. Use a voltage divider (two resistors: 1K and 2K) on the Arduino TX line to reduce the voltage to approximately 3.3V before connecting to HC-06 RX. The HC-06 TX pin can safely connect to Arduino RX pin as it outputs 3.3V logic which Arduino recognizes as HIGH. Always verify your specific module's voltage specifications before connection.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I change the HC-06 module name and PIN code?\u003c\/summary\u003e\n\u003cp\u003eConnect the module to a serial terminal at 9600 baud and send AT commands: AT+NAME=YourModuleName to change the Bluetooth device name visible during pairing, and AT+PSWD=1234 to set a custom 4-digit PIN code. Note that some modules require the EN pin to be pulled high to enter AT command mode. After sending AT commands, the module responds with OK if successful. Changes take effect after module restart.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum transmission range of HC-06?\u003c\/summary\u003e\n\u003cp\u003eThe HC-06 Class II module has a nominal range of 10-20 meters in open space with clear line-of-sight. Actual range depends on environmental factors including obstacles, metal shielding, RF interference from Wi-Fi and microwave devices, antenna orientation, and power supply quality. Indoor range typically reduces to 5-15 meters due to wall attenuation. For extended range applications, consider upgrading to Class I modules with external antennas.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
